The Bosch Rexroth DBET-6X/50G24K4V (R901000842) is a high-performance industrial hydraulic valve designed for reliable pressure limitation in accordance with the command value signal. This direct-actuated proportional pressure relief valve features a spool symbol P T and is capable of handling a maximum pressure of 350 bar. It is equipped with an electrical connection that conforms to EN 175301-803, featuring a connector pole with PE functionality.
With its size 6 CETOP D subplate mounting design, this valve offers ease of integration into various hydraulic systems. The connection diagram adheres to both NFPA T3.5.1 R2 and ISO 4401 standards, ensuring broad compatibility. The DBET-6X/50G24K4V operates on a supply voltage of 24 VDC and includes an electrical connector that matches the specifications of the valve's electrical requirements.
With a maximum flow capacity specified by the manufacturer, this valve accommodates a range of fluid types including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its construction includes FKM seals for enhanced durability against aggressive media.
The Bosch Rexroth DBET series valves are recognized for their precise control capabilities enabled by the proportional solenoid operation. The solenoid features a central thread and detachable coil for maintenance convenience. Users can adjust system pressures steplessly due to the valve's responsive design to electrical command values.
Additionally, the device offers user-friendly features such as individually adjustable ramps for both upward and downward settings and fine-tuning options for the command value pressure characteristic curve. With its robust design and advanced control features, the Bosch Rexroth DBET-6X/50G24K4V valve is an essential component for sophisticated hydraulic systems requiring precise pressure regulation.

General information
Proportional pressure relief valves of type DBET are remote control valves with seat design and are used for system pressure limitation. Operation by means of a proportional solenoid with central thread and detachable coil. The interior of the solenoid is connected to port T or Y and is filled with the hydraulic fluid. Dependent on the electric command value, these valves can be used to steplessly set the system pressure to be limited. The valves mainly consist of the housing (1), a proportional solenoid (2), the valve seat (3) and the valve poppet (4).
Basic principle
For the setting of the system pressure, a command value is specified at the control electronics. Dependent on the command value, the electronics actuate the solenoid coil with electric current. The proportional solenoid converts the electric current into mechanical force that acts on the valve poppet (4) via the armature plunger (5). The valve poppet (4) pushes onto the valve seat (3) and blocks the connection between port P and T or Y. If the hydraulic force on the valve poppet (4) equals the solenoid force, the valve controls the set pressure by lifting the valve poppet (4) off the valve seat (3) and thus enabling hydraulic fluid to flow from port P to T or Y. If the command value is zero, the control electronics only apply the minimum control current to the proportional solenoid (2) and the minimum set pressure is set.

Pressure in port P dependent on the command value (flow = 0.8 l/min)
| 1) | 1) With valve type DBET, the manufacturing tolerance at the external amplifier can be changed using the command value attenuator potentiometer "Gw". The digital amplifier is set using the "Limit” parameter. Here, the control current according to the technical data must not be exceeded. In order to be able to adjust several valves to the same characteristic curve, do not set the pressure higher than the maximum set pressure of the pressure rating with command value 100%. |
